2017 ACURA NSX: Introduction
History When the original Acura NSX made its
debut 25 years ago, it forever changed the supercar universe by
combining scintillating sports car styling and athletic
performance—common traits long associated with the exotic car
segment—with a new dimension of quality, exceptional ergonomics,
comfort, and dynamic poise. The NSX introduced and defined Acura's
approach to "Precision Crafted Performance" with its cutting-edge design
and innovative technology that provided accessible supercar performance
for real drivers in the real world.
By making use of advanced new technologies such as a lightweight yet
rigid all-aluminum monocoque body/chassis and a mid-mounted transverse
V6, the original NSX challenged the conventional wisdom for a supercar.
Its high-revving V6 engine featured a number of innovative production
car technologies including forged pistons, titanium connecting rods and
VTEC valve train.
Moreover, the NSX sought a more intimate connection between the car,
the driver and the road underneath them, pursued through essential
design elements – light weight, open and airy cockpit, and excellent
ergonomics – creating an altogether new and paradigm-challenging
definition of supercar performance.
Next Generation Concept The overarching concept
for the design and development of this next-generation NSX was the idea
of a "human-centered supercar," one that places the driver at the center
of its mission in each and every element of its design and dynamic
performance.
Respecting the foundational concepts of the original NSX—accessible
supercar performance, everyday drivability, and openness to new
technology—this next-generation NSX pursues an altogether new and
revolutionary concept of Acura supercar performance – melding timeless
NSX values with advanced technologies to create a
New Sports eXperience.
Advanced Fundamentals (Timeless NSX Values)
First and foremost, the engineering team felt a tremendous
responsibility to continue the fundamental innovation pursued by the
original NSX team. Four foundational philosophies are fundamental to the
timeless NSX values and essential to realize the new NSX concept and
goals:
- Total Airflow Management – a wholistic approach to
thermal management and aerodynamic performance that supports and
enhances dynamic response and high-speed stability without the need for
active aero devices
- Human Support Cockpit – a cabin that supports the driver and amplifies the driving experience with no sacrifice to comfort or everyday usability
- Multi-Material Body – light and ultra-rigid body,
applying material, construction and joining methodology optimized to the
mission of each body component
- Advanced Sports Package – optimizing the design and
packaging in all the above aspects—the human package, the body, and
finally the key components of the power unit to lower and center the
mass of the vehicle.
Advanced Technologies With these fundamentals in
place, NSX engineers could effectively develop technical solutions
needed to deliver the New Sports driving experience they sought.
To fully realize this
New Sports eXperience, Acura electrifies the advanced fundamentals by leveraging its longstanding Direct Yaw Control knowhow through its
Sport Hybrid Super Handling All-Wheel-Drive (SH-AWD) system, the first of its kind in the supercar realm.
The NSX concept for "zero delay" is more than acceleration, actually
involving every aspect of the driver interface … the capacity to
directly respond to the driver's demands in all three phases of driving:
Go, Stop, Turn (acceleration, braking and cornering). The NSX's
advanced power unit supports this achievement. Zero delay acceleration
and active AWD traction power the NSX out of corners. Energy recovery
supports direct and linear braking. And power strategically applied to
the wheels directly creates a yaw moment to help turn the car according
to the driver's will.
Marrying new approaches to vehicle design fundamentals, including
advanced body construction, component packaging and aerodynamic
optimization, with an advanced and electrified new expression of Acura's
direct yaw control concept results in a supercar that faithfully
translates the inputs of the driver with incredible fidelity and zero
delay while minimizing the driver's workload—qualities that define the
New Sports eXperience.
Design, Development and Manufacturing
Development of the next-generation NSX involved a global team of
engineers and designers, with development of the Sport Hybrid power unit
centered in Tochigi, Japan. Development of the body, chassis,
electrical, interior and other vehicle technologies including total
system integration, was concentrated in Raymond, Ohio. Initial styling
design for the NSX was conducted at the company's Wako design studio in
Japan, and was evolved for production by the Acura Design Studio in Los
Angeles.
Throughout its roughly four-year development, the fundamental
"human-centered supercar" concept for the next-generation NSX remained
clear and consistent. However, the technologies and means by which the
R&D team would realize their concept underwent a process of
continual improvement and evolution, most notably in the area of engine
design. Whereas the original direction called for a transverse-mounted,
normally aspirated V6, the NSX development concept evolved to a new and
more challenging approach: an all-new bespoke twin-turbocharged,
longitudinally mounted V6. This radical re-imagination of the engine
design had profound implications for every element of the NSX design—the
package, cooling, aerodynamics, chassis and more.
The NSX has been tested and tuned on streets and race circuits around
the world. Primary development was conducted at the Transportation
Research Center adjacent to Honda R&D Americas Ohio Center as well
as the Honda Takasu proving ground in northern Japan before moving to
tracks such as Virginia International Raceway and the famed Nürburgring,
followed by global "genteki" events ("at-the-spot" verification) which
took NSX on public roads throughout the U.S. and Europe and beyond.
Construction of the NSX will take place at the new Performance
Manufacturing Center (PMC) in Marysville, Ohio. The PMC was designed to
innovate both the means and the methods of producing low-volume
specialty cars and to realize challenging new ideas for next-generation
craftsmanship and quality established by the NSX manufacturing team.
The PMC employs approximately 100 associates, including 70 highly
skilled manufacturing technicians engaged in body construction,
painting, assembly and quality confirmation of the NSX. Among its many
innovative processes is the use of robotic MIG welding for the
construction of the NSX's aluminum space frame.
The NSX's bespoke twin-turbocharged V6 engine is assembled by master
engine builders at the company's engine plant in Anna, Ohio. The engine
is broken in on a dyno so that it's track-ready when it leaves the
factory. Then it's mated to a direct drive motor (part of the hybrid
system) and precision balanced as an assembly. Its bespoke 9-speed dual
clutch transmission is then attached to the engine and this portion of
the total power unit is sent to the PMC. The Twin Motor Unit (TMU) and
other hybrid system components are built in Japan and shipped to Ohio
for final assembly, completing the overall power unit.
2017 ACURA NSX: Dynamic Performance
Dynamic Concept The NSX was created to
revolutionize supercar performance, delivering a more vivid, immediate
and intuitive dynamic experience with zero-delay acceleration, braking
and handling – such that the vehicle responds according to the "will" of
every driver's inputs, but truly comes "alive" in the hands of skillful
drivers. Fundamental dynamic concepts are as follows:
- Ultimate Rigidity – via the multi-material body,
providing the foundation for the zero-delay translation of driver inputs
through steering, throttle and brakes. The same strong foundation
directly reacts the yaw moment created from our advanced technologies
- Human Fit – exemplified by a cockpit that is
optimized in every element of its design to support the driver and
clarify the driving experience while providing outstanding comfort and
class-leading ergonomics
- Advanced Sports Package – optimizes the design and
packaging of all major vehicle systems to lower and center the mass of
the vehicle for incredible handling and dynamic response
- Total Airflow Management – a new airflow management
approach gives the NSX the superlative airflow management expected of a
next-generation supercar, cooling is ducted through heat exchangers and
then precisely directed to various exit locations to optimize drag and
downforce.
- Advanced Zero Delay Technologies – the capacity to directly respond to the driver's demands in all three phases of driving: Go, Stop, Turn
- On Rails Cornering – translating driver inputs into
vehicle responses with incredible fidelity and amplifying the
capabilities of the driver and the car via direct yaw control with
next-generation Sport Hybrid Super-Handling All Wheel drive
- Fade-free braking – powerful, linear, predictable
and virtually fade-free braking performance in all driving conditions
via the seamless integration of high-performance mechanical (Brembo
hydraulic) braking and hybrid motor assisted electro-servo
(regenerative) braking
- Acceleration – instant acceleration G feeling from
the moment the driver engages the throttle, enhanced by the immediate
torque response of three electric motors working in concert with the
bespoke, twin-turbocharged V6 and 9-speed dual clutch transmission
(9DCT)
FUNDAMENTAL ZERO DELAY TECHNOLOGIES:
Ultimate Rigidity (Multi-Material Body) Like the
original Acura NSX—the world's first all-aluminum supercar—the all-new
NSX has a cutting-edge structure: its Multi-Material body, utilizes new
materials and construction methods to create a platform with
unprecedented dynamic rigidity.
- Space frame torsional rigidity that surpasses anything in its class
- Each suspension point is attached to precision machined
castings—including the world's first automotive application of ablation
casting technology—to provide the ultimate, local attachment point
rigidity
- Unparalleled platform rigidity transmits the full feeling of the
Power Unit, suspension, and steering directly to the driver with zero
delay, while maximizing the effectiveness of Direct Yaw Control to
improve vehicle dynamics
Human Support Cockpit From its minimalistic yet
contemporary design to its careful application of materials in the seat
and steering wheel the team sought to support the driver and clarify the
driving experience. The interior of the all-new Acura NSX has a
"human-centric" ergonomically-enhanced design theme for both the driver
and passenger.
Since steering feel and performance are such an important aspect of
the on-rails handling nature of the high-performance NSX, unusually
detailed attention was paid to perfecting the steering wheel. This
included maximizing grip via a more ergonomic shape and increasing
surface contact for the hands, as well as easier operation of the paddle
shifters.
To maximize forward visibility, specially designed A-pillars made of
ultra-high-strength steel were incorporated into the design of the
all-new Acura NSX. These new pillars are actually a full inch thinner
than those of the original NSX, but offer enhanced safety performance.
Advanced Sports Package The new Acura NSX
Advanced Sports Package is a design philosophy that seeks to optimize
the design and packaging of all major vehicle systems—the body, chassis
and interior, including the mid-mounted Sport Hybrid Power Unit (engine,
Direct Drive Motor and 9DCT) and key hybrid components including the
Intelligent Power Unit (containing the lithium-ion battery pack), PDU
and the TMU—to lower and center the mass of the vehicle for optimal
handling and dynamic response.
While maintaining ground clearance similar to the highest volume
sports car and expanding the head room to accommodate a 95th percentile
American male, the new NSX has the lowest center of gravity among its
core competitors.
Total Airflow Management "In many ways, with the
design of the all-new Acura NSX, you literally have form following
function, so this was a really exciting vehicle to work on as an
aerodynamicist," says Thomas Ramsay, the Aerodynamics and Cooling
Project Leader on the new Acura supercar.
NSX's body shape was effectively designed to minimize aerodynamic
drag while creating balanced front-to-rear downforce through a total
airflow management focus on utilizing airflow through each vent, while
extracting maximum energy from the airflow field to cool the brakes and
manage power unit thermal loads.
Through extensive research and development, the NSX aerodynamics team
determined that placing approximately three times as much downforce at
the rear of the vehicle relative to the front of the car would provide
the optimal downforce balance for high-performance driving as well as
everyday functionality. Further evidence of the superior aerodynamics
engineered into the NSX is that its high level of downforce is
accomplished without the need for active aerodynamic bodywork or other
devices.
Advanced Zero Delay Technologies: With the Sport Hybrid SH-AWD, zero delay performance is ensured in virtually any driving scenario:
- When accelerating, the system provides instantaneous torque via its
three electric motors—the rear direct drive motor and front Twin Motor
Unit—that is maximized at all four tires when accelerating or powering
out of corners.
- When trail-braking into a corner, the system utilizes the front TMU
for enhanced deceleration—the advanced braking system works in concert
with the vehicle's mechanical brakes to precisely decelerate, and the
Direct Yaw Control delivers precise and immediate turn-in performance
while allowing drivers to point their eyes toward the corner apexes.
- When exiting a corner, the driver can pick up the throttle earlier
and with more confidence and accelerate with added precision and as well
as reduced workload.
"Using Honda's original beta method to consider overall handling
performance, we've been exploring direct yaw control torque vectoring
for over two decades," says Ted Klaus, Acura NSX Global Development
Leader. "With the development of the Sport Hybrid Super-Handling All
Wheel Drive System, we can take advantage of the superior responsiveness
of the electric motor characteristics within the system powered by an
independent Battery to significantly expand the benefits of direct yaw
control."
By taking advantage of the immediate torque response of the system's
three electric motors to heighten the control and effectiveness of
direct yaw control, the Acura NSX Sport Hybrid SH AWD system elevates
any driver's confidence and performance driving capabilities while
extracting more performance from the car.
2017 ACURA NSX: Sport Hybrid Power Unit
Concept The exceptional dynamic capabilities
and zero-delay responses of the new NSX are enabled by the exploitation
of advanced powertrain technologies. This concept of utilizing
next-generation technology to deliver a New Sports eXperience is
epitomized by the adoption of a Sport Hybrid power unit.
At the heart of this new hybrid power unit is a bespoke, mid-mounted
twin-turbocharged, 75-degree 3.5-liter DOHC V6 engine with dry sump
lubrication, mated to an all-new 9-speed dual clutch transmission (9DCT)
and Direct-Drive Motor. This is augmented by the front Twin Motor Unit
(TMU) driving the front wheels. The NSX Sport Hybrid power unit offers
exceptional horsepower and torque with a broad powerband for tremendous
throttle response and acceleration. Total system peak output is
estimated at 573 horsepower—500 horsepower from the gasoline engine and
73 horsepower from the front TMU.
Twin-Turbocharged V6 Engine Featuring a wide
V-angle of 75 degrees to help lower the center of gravity, the NSX's
twin-turbocharged V6 engine achieves the best balance between power
production, overall compactness and reduced mass. With a displacement of
3.5 liters, it combines both direct injection and port injection, along
with Variable Timing Control (VTC) to deliver optimal camshaft phasing,
for precision combustion control throughout the entire rpm band while
simultaneously achieving high power output and performance at high
engine speeds.
Making use of an electronic wastegate for each turbocharger for
faster response as well as more precisely varying vane positioning, the
single-scroll turbocharger design allows for the use of smaller turbos
to reduce weight and improve packaging, while still meeting power and
performance benchmarks. Furthermore, their single-scroll design allows
for more efficient collection of exhaust as it escapes from within the
cylinders.
To reduce the response delay that is associated with turbocharged
powerplants, the rear Direct Drive Motor acts directly on the engine's
crankshaft and works in unison via a sophisticated algorithm to realize
direct, high output, high torque acceleration performance. The enhanced
efficiency of this design arrangement is particularly noticeable in
normal everyday driving when accelerating from a low engine speed.
Additionally, the rear electric motor also acts as a generator to
provide supplemental power to the vehicles lithium ion battery pack,
which also powers the front-mounted TMU.
Other key engine design elements include a sand-cast engine block,
lightweight and compact cylinder heads, FC thermal spray coating on the
engine block cylinder sleeves (for higher thermal efficiency, weight and
compactness) and a dry sump lubrication system that significantly
reduces the engine's center of gravity—allowing 61 mm reduction from the
crank center to the engine bottom versus a conventional wet sump—while
ensuring effective lubrication at high cornering speeds.
The NSX has a compact valve train utilizing swing arm-type valve
actuators, helping to reduce the inertial weight of the valve train and
allowing a more compact head structure. The structure is similar to
those found in some Honda racing engines. Intake and exhaust variable
cam timing (VTC) is deployed to provide an excellent balance of high
power, torque, fuel economy, and emissions.
9-Speed Dual Clutch Transmission with Direct Drive Motor
The new 9-speed dual clutch transmission works in concert with the
engine and Direct Drive Motor to make full use of the power unit's broad
power band, producing lightning quick gear changes that support the
NSX's zero-delay response. As a key component of the Advanced Sports
Package, the 9DCT has been optimized for compact size, low mass and low
CG.
The 9DCT has a very wide ratio range that allows for optimal gear
selection in all driving conditions. First gear ratio is configured for
maximum vehicle launch acceleration, while the close-ratio gears (2nd
through 8th) are perfectly matched to make the most of the power unit's
power band. Conversely, high gear (9th) has been optimized for fuel
efficiency during steady-state highway cruising.
In efforts toward compactness and reduction of mass, the clutch and
the differential are uniquely situated side-by side in a common housing.
By adopting this design, overhang from the rear axle is minimized while
the center of mass is moved forward.
Other advanced technologies incorporated into the 9-speed DCT are:
- Electronically-operated wet dual clutch, a high-rigidity shift fork,
double-cone synchronizer, and an electronic shift actuator to more
precisely synchronize power unit torque with shift timing for the
quickest and smoothest shifts possible
- Precision surfaced high-efficiency hypoid bevel gear tooth shape for all gears for improved operation with reduced gear noise
- Addition of two oil "rooms" within the transmission housing for more efficient and higher-capacity cooling
- Clutch case and differential carrier integrated into the transmission for a more lightweight and compact structure
- Lightweight high-strength gearbox case
- Multiple-plate limited slip differential (LSD) provides increased
traction when accelerating and cornering at the limits of adhesion
Twin Motor Unit (TMU) The exceptional direct and
linear acceleration and dynamic response of the new NSX is enabled in
part by its front-mounted Twin Motor Unit (TMU). It is a major driving
force in creating the vehicle's superlative zero-delay acceleration and
can directly generate a yaw moment to support turning, and also recovers
braking energy during deceleration.
The TMU provides instant torque as well as AWD traction, allowing
direct and stress free launches from start. In addition to improving
0-to-60 mph and quarter-mile times, this zero-delay acceleration
response allows the driver to experience a heightened sense of G-loading
that invigorates the senses, an adrenaline rush as accelerative forces
push the body into the seat. Most importantly, the Sport Hybrid SH-AWD
works in harmony with the poised chassis and brake system to provide
intuitive brake pedal and steering feel so the driver always feels
completely in control.
The TMU is geared to support acceleration up to 200 kph, but
continues to support Direct Yaw Control at all vehicle speeds. It is
also a key enabling technology for driving in the Quiet mode setting of
the IDS, allowing for hushed vehicle operation by operating the NSX as
an electric vehicle.
Intelligent Power Unit (IPU)/Power Drive Unit (PDU)
The IPU integrates the lithium-ion battery pack and a high-voltage
distribution bus bar, with voltage distribution controlled by the PDU.
The newly developed lithium-ion battery pack allows for increased energy
density and improved electrical output when compared to similar systems
in existing vehicle models.
The Power Drive Unit (PDU) is centralized in a low position within
the vehicle, hidden below the center console. The high-voltage
lithium-ion battery is mounted within the Integrated Power Unit (IPU),
which is in turn mounted behind the driver and passenger, forward of the
firewall.

2017 ACURA NSX: Multi-Material Body
Concept To realize the New Sports eXperience
and to support new concepts in vehicle dynamics—in particular the direct
yaw control effected by the torque vectoring capabilities of the
front-mounted TMU and the direct, zero-delay response of the chassis to
driver inputs—the NSX engineering team was challenged to create a new
concept for body design that delivered ultimate rigidity while
minimizing weight and meeting other critical targets such as visibility,
crash safety performance and durability/quality/reliability (DQR).
The final result of this engineering challenge is the NSX
multi-material space-frame which achieves structural rigidity far
superior to its top-in-class competitors. More importantly, NSX drivers
will feel their inputs directly translated to the car's actions with
zero delay, while simultaneously allowing the maximum potential of the
Sport Hybrid SH-AWD system to be felt by the driver.
Multi Material Space Frame The aluminum-intensive space frame utilizes extruded and cast parts to provide exceptional rigidity and light weight.
In order to directly translate the direct yaw moment generated by the
TMU, and to precisely deliver feedback to the driver with zero delay,
individual aluminum castings have been utilized at each and every
attachment point for the suspension. These castings are supported in all
three dimensions (x, y, z) by optimized extrusions.
Utilizing Global and local optimization routines, each casting and
extrusion was analyzed for potential weight savings. The result is that
most extrusions have custom wall thickness and many have a different
wall thickness for each of their sides.
Steel stampings have also been added to the architecture in certain
areas where energy absorption is required, with supplemental aluminum
stampings used where low weight is a key consideration. The front floor
panels are constructed of carbon fiber core.
Ablation Cast Nodes One of the most difficult
design challenges in the development of the all-new Acura NSX was to
minimize the front and rear overhangs of the vehicle while managing
energy absorption in key areas for crash safety performance
and to
maintain desired structural rigidity. To solve the issues of
crashworthiness and occupant protection, a particular challenge in
mid-engine vehicles, traditional aluminum castings were rejected due to
their brittle characteristics. Instead, engineers have applied an
innovative new technology called "ablation" casting, an all-new material
application and a world first in the automobile industry.
Jointly developed with Alotech, ablation casting technology is being
utilized in the creation of six joining members, or nodes—two upper and
two lower nodes in the front frame and two rear nodes. The front upper
and rear nodes also serve as ultra-rigid suspension mounting points. The
ablation casting process allows for the fine-tuning of both the cast
part's shape, as well as the material properties of the castings in the
energy-absorbing areas of the vehicle, while minimizing weight in the
form of a hollow part with optimized wall thickness.
Unlike traditional castings, the high-strength and ductile properties
of the aluminum ablation cast members allow these sections of the
space-frame to progressively crush and are designed to withstand
tremendous loads of up to 210 kN without breaking.
3-Dimensional Bent and Quenched Ultra-High-Strength A-Pillar
For the A-pillars, new advancements in ultra-high-strength steel parts
forming provided a perfect solution that met the engineering team's
goals for safety performance while maximizing forward visibility for the
driver by reducing the A-pillar width. The original NSX was known for
its outstanding forward visibility, giving drivers a feeling of being
connected to the road, and this design attribute was considered
essential to preserving a core characteristic of the NSX driving
experience.
The NSX A-pillars have been precisely crafted using an all-new,
three-dimensional forming and tempering process that allows for a
complex parts shape with ultra-high tensile strength of 1,500
megapascals. This "3D bent and quenched" component is heated and then
robotically bent. During the bending process the part is cooled and
tempered (quenched) using water jets. This process enables a very small
section A-pillar with precise shape specification and tolerances, yet
meets the increased structural rigidity for roof-crush performance
requirements.
The design and construction of the A-pillars in the new NSX represent
the world's first application of a three-dimensionally formed,
ultra-high-strength steel system to be used in this manner within the
automotive industry.
Carbon Fiber Core Floor When evaluating material
composition and placement throughout the body, the design team
determined that carbon fiber core would serve as the ideal material for
the floor section forward of the seats. In addition to its light weight,
this material is strong enough to handle the loads of driver and
passenger placed upon it for vehicle ingress/egress. If aluminum had
been used, the aluminum sheeting would have required additional
cross-member frame support beneath it; this would have added additional
weight.
Construction Techniques A number of innovative
construction techniques are used in the manufacture and assembly of the
all-new Acura NSX at the company's new Performance Manufacturing Center
in Marysville, Ohio.
100 percent of the aluminum space frame components are joined by
Robotic Metal Inert Gas (MIG) welding, the first time to be applied in a
mass-produced automobile on this scale. To aid the accuracy of the
robotic weld process, the PMC utilizes an innovative rotating trunnion,
or rotisserie-type, jig that rotates the part into the optimal position
for the robotic weld arms, another first for automobile body
construction.
Exceptionally high-quality and precise space-frame construction is
accomplished via this innovative methodology which combines highly
precise robotic control of the weld process with the advanced skills of
PMC weld technicians. A robust in-line quality confirmation process, for
both the quality of the weld and conformity of part to established
specs, involves confirmation by both robotic measuring equipment and by
highly skilled weld technicians at every stage of the construction
process.
Other Exterior Body Design Highlights:
- Aluminum and composite exterior body panels
- Optional carbon fiber roof panel
- SMC rear trunk
- Flush outer door handle design
- Magnesium fuel door hinge
Total Airflow Management The NSX's team of
aerodynamicists utilized a new total airflow management approach to give
the NSX the superlative airflow management one expects of a
next-generation supercar, while simultaneously providing the effective
and highly efficient thermal management required for its hybrid power
unit. There are seven different heat sources in the hybrid-based
powertrain—the 3.5-liter V6 engine, twin turbochargers, the 9-speed DCT,
Dual Clutch system, Power Distribution Unit, Twin Motor Unit. To
provide efficient cooling, airflow is managed through 10 different heat
exchangers.
Through the use of computational fluid dynamic (CFD) simulations as
well as testing of 40-percent scale models in the company's advanced
wind tunnel facility in Ohio, the NSX development team fine-tuned the
various body shapes, intake and exhaust vents and vehicle strakes to
reduce aerodynamic drag, create downforce, maximize cooling and
efficiently exhaust unwanted heat.
The highly innovative total airflow management developments that were
discovered and implemented into the new NSX by the Ohio team were later
confirmed at the company's full-scale/moving ground plane wind tunnel
in Japan.
Total Airflow Management Design Highlights:
- Efficient cooling openings at the front of the vehicle to maximize
cooling airflow across the key heat exchangers located within the front
section (front engine radiators, twin motor unit cooler, condenser, the
transmission gear cooler, hybrid Power Distribution Unit)
- Optimized front exit flow paths considering total flow, maximum
downforce, low coefficient of drag, and achieving downstream flow
structure to feed the mid-engine air inlets
- Wheel wake management vents work in conjunction with fender vents to
stabilize airflow down the side of the vehicle, allowing the air to
enter the signature side intakes for efficient cooling. The air that
enters the side intakes is distributed to three areas: engine intake,
engine room cooling, and turbo intercoolers.
- Air flowing over the roof and down the rear hatch glass is captured
to feed the transmission clutch cooler and introduce engine room cooling
flow.
- A rear diffuser works together with the rear spoiler and taillight
slots to generate significant downforce and effectively manage the air
wake generated behind the vehicle.
- Optimization of front/rear downforce distribution for improved handling and stability
Human Support Cockpit To develop an interior
with exemplary ergonomics in terms of comfort and functionality, the
Acura design team utilized a number of test drivers with wide-ranging
driving backgrounds—from "regular" people to professional race
drivers.—in order to gather information to improve all aspects of driver
feel and comfort in the NSX.
Materials such as leather and Alcantara were carefully selected for
the perfect combination of luxury comfort and dynamic driving support
(such as lateral grip). Likewise, the center console/controls—designated
as the Simple Sports Interface—have been designed to minimize the
potential for distractions from the most important function—driving.
Stylish as well as structurally rigid
and lightweight, the
seats in the new NSX have been designed to offer superlative comfort and
support. Alcantara is placed in the center section of the seat to
increase lateral grip, while smoother leather is applied on the bolsters
to allow freedom of torso rotation during cornering as well as easy of
ingress and egress. Developed through extensive testing and pressure
mapping measurements, these seats more in conjunction with the padded
center console and door panel to provide whole body support during high G
cornering.
2017 ACURA NSX: Chassis
Concept The all-new 2017 Acura NSX chassis
carries forward the tradition of sophisticated engineering and advanced
design while taking on-rails handling performance, combined with
sophisticated ride quality and refinement to an all-new level in the
supercar class.
Athletic performance is assured through the Advanced Sport Package, a
design and packaging concept that sees major components including the
powertrain, fuel tank and lithium-ion battery pack optimized for
compactness as well as outstanding weight distribution and an extremely
low center of gravity (CG).
The platform of the NSX not only possesses the highest degree of
structural rigidity ever engineered into an Acura vehicle, it also
achieves the lowest levels of noise, vibration and harshness (NVH) of
any competitive vehicle.
The highly rigid platform structure, advanced front and rear
suspension with Magnetic Ride (MR) dampers, finely-tuned variable gear
ratio electric power steering and next-generation Super Sports Brake
Concept featuring Brembo performance brakes and regenerative braking
capability inspire absolute driving confidence—whether taking a sweeping
turn at high speed on the race track, negotiating a multitude of tight
corners on a winding mountain road or taking an extended trip out on the
open highway.
Drivetrain Packaging With the newly designed
twin-turbocharged 3.5-liter V6 engine, special consideration was given
to how the engine would be secured to the chassis in order to achieve
the highest structural rigidity while producing the lowest levels of
noise, vibration and harshness (NVH). The solution was to create an
engine cradle system that combines hydro-engine mounts with a rigid
aluminum sub-frame plate that simultaneously supports the engine while
acting as a vibration and noise inhibitor. Engine mounts are ideally
located to minimize pitch and roll movement of the powertrain mass.
Testing and analysis demonstrated that this novel configuration provides
notably improved vehicle handling performance while exceeding targeted
NVH levels.
Suspension The NSX's all-aluminum, fully
independent front and rear suspension system, equipped at all four
corners with third-generation active magnetorheological (MR) dampers, is
optimized for high-strength, low unspring weight, and supercar response
while maintaining a high degree of comfort and ride compliance.
Front Suspension
The all-aluminum front suspension has been optimized with compact and
lightweight components and suspension geometry developed for superior
handling performance, crisp and communicative on-center steering feel,
and excellent stability.
Additional specifics of the front suspension that help achieve exceptional handling performance and refinement include:
- Double wishbone suspension design
- Double ball joint lower arm design to eliminate the TMU drive force related steering feedback
- Third-generation Acura MR dampers with even quicker response and the widest-ever damping range
Rear Suspension
Featuring lightweight all-aluminum components, the rear suspension employs a sophisticated independent multi-link design.
Rear suspension features:
- Optimized multi-link geometry
- High lateral rigidity
- Third-generation Acura MR dampers with even quicker response and the widest-ever damping range
Steering "It was a huge challenge to create a
lively and communicative Electric Power Steering (EPS) for the driver
that would be truly worthy of a next-generation Acura NSX," said Chris
Dundon, Chief Chassis Engineer. "But by optimizing the mechanical
components within the system, plus careful tuning of the software, we
were able to achieve our goal of delivering highly responsive steering
with outstanding driver feel."
A key design feature to help improve driver feel through the Electric
Power Steering (EPS) system was the addition of dual ball joints for
the front suspension lower arms, providing for substantially better
"oneness with the road," according to Dundon.
The NSX makes use of a dual-pinion (with rack-mounted assist motor)
electric power steering (EPS) system with a variable gear ratio. When on
center, the ratio remains constant and is tuned for optimal high speed
control and stability. Off center, the gear ratio becomes quicker for
improved turn-in and maneuverability at low and mid speeds. This also
minimizes the need for hand-over-hand motion to help drivers keep their
hands on the steering wheel.
Furthermore, this sophisticated steering system links the vehicle
stability assist (VSA) and EPS to help detect handling instability on
slippery roads and under braking for greater vehicle control and an
increased safety margin when driving in adverse conditions.
Next-Generation Super Sports Brake Concept
Seamlessly integrating both mechanical (friction) and electric-servo
(regenerative) brake systems, the NSX provides exceptionally precise,
linear and fade-free brake performance in almost any driving condition.
The Brembo braking system consists of large six-piston aluminum
monoblock calipers with two-piece 14.5-inch ventilated rotors up front.
The rear uses four-piston aluminum monoblock calipers and 14.0 inch
ventilated rotors. A two-piece brake rotor eliminate rotor distortion at
high heat allowing for consistent pad to rotor contact and improved
heat dissipation. Themonoblock brake calipers have been designed with
high rigidity to provide even pressure distribution. Ultra
high-performance carbon ceramic brake rotors are available as a
factory-installed option.
Excellent brake cooling at both front and rear has been achieved as
an integral part of the total airflow management package. Extensive
research and development work has been done to maximize the cooling
efficiency and performance of the rear brake system. Typically,
effective brake cooling at the rear of a mid-engine vehicle is difficult
due to component packaging and proximity of the engine and
transmission. NSX engineers devised a clever solution by creating
openings beneath the vehicle and utilizing portions of the hollow rear
sub-frame as ducts to force feed air to the rear brakes.
Wheels/Tires The standard wheel design package
for the new NSX includes lightweight alloy wheels with "Y"-style spokes
wrapped in Continental Conti-Sport Contact 5P tires (245/35ZR19 front;
305/30ZR20 rear) developed jointly with Continental.
The unique "Y-wheel" design is a result of the NSX engineering team's
extensive research to find the strongest spoke structure while using
the least amount of material in order to save unspring weight. Forged in
high-strength aluminum, the result is a weight savings of nearly 7
pounds per set and lower total weight than any wheels of similar size
and material composition within the NSX's segment.
Additional wheel/tire options, including a track-focused tire, will be available.
Fuel Tank Finding the ideal weight distribution, center of gravity, shape and placement of
the
fuel tank was a difficult design task, especially when taking into
consideration protection in the event of a rear-end collision. The
solution was a design that uses twin tanks composed of a specialized
resin material that allowed for tremendous flexibility in the freedom of
the shape of the fuel tanks for optimal packaging and enhanced safety.
The tanks are centrally located between the engine and the IPU.
Integrated Dynamics System (IDS) The NSX
Integrated Dynamics System (IDS) provides the driver with four
selectable dynamic modes—Quiet, Sport, Sport+ and Track. The system
integrates all of the vehicle's dynamic chassis and powertrain
systems—steering, brakes (mechanical and electro-servo), throttle,
vehicle stability assist, magnetorheological dampers, engine,
transmission, and Sport Hybrid SH-AWD control systems.
From the available all-electric operation of Quiet mode to the closed
circuit, maximum performance capacities of Track mode, IDS
progressively dials up the dynamic characteristics of the vehicle based
on the needs of the driver and the driving environment.
In addition to these dynamic system variations, IDS varies cabin
sounds via Active Exhaust Valve (AEV) and new Intake Sound Control
(ISC). ISC uses twin pipes with an electrically controlled valve to vary
the sound being transmitted from engine air intake system to twin
outlets in the rear uppermost portions of the cabin. Utilizing these
technologies, IDS is able to fine-tune cabin sound quality and volume to
match the dynamic character of the vehicle in Quiet, Sport, Sport+ and
Track modes. Of note, there is a full 25 dB volumetric sound difference
between Quiet and Track modes—a tremendous variance in audible
sensation.
Quiet
Quiet mode prioritizes electric-only
driving at lower speeds, maximizing energy efficiency and minimizing
cabin sound. The vehicle uses the TMU for initial launch from a
standstill. When power demand requires the engine, it starts more
quietly than in other modes and maximum engine speed is limited to 4,000
rpm, while the Active Exhaust and Intake Sound Control valves are
closed for a more hushed operation. The transmission shift map also
prioritizes lower engine speeds. The Driver Interface (tachometer and
center console information display screen) features a cool and quiet
blue color.
Sport
Sport mode takes advantage of the Sport
Hybrid system to offer the driver a direct responsive vehicle or a more
relaxed vehicle according to their driving inputs. Compared to Quiet
Mode, it eliminates the 4,000 rpm limit on the engine and provides a
more aggressive throttle map for quicker response. A more aggressive
transmission shift map holds gears longer and allows higher rpm shift
points. The Intake Sound Control system and the Active Exhaust Valve are
activated, allowing exhaust and intake sound to permeate the cabin for a
more emotional driving experience. Like the Quiet mode, sport mode
provides idle stop function. The Sport setting is the default setting in
normal vehicle operation.
Sport+
Sport+ prioritizes maximum drivetrain
response and dynamic performance with faster up- and down-shifts of the 9
DCT and still more aggressive throttle mapping. Maximum use of the
electric motor torque provides more explosive acceleration. Increased
agility is achieved by harmonizing a more aggressive Direct Yaw Control
setting that works in concert with the magnetorheological dampers, Agile
Handling Assist, and the Electric Power Steering System—perfect for a
spirited drive on a winding road. It also offers the driver a higher
degree of steering feedback, while intake and exhaust note sounds via
Active Sound Control are further increased for an even more exhilarating
and emotional driving experience. The TFT Meter sports an aggressive
yellow "con-trail" along the tachometer needle supporting easy
recognition of engine RPM. Red highlights for the center console
information display also reinforce that the driver is in now in Sport+
mode.
Track
Optimized for circuit driving, Track mode
invokes the most aggressive settings and parameters to deliver the
fastest and most consistent lap times possible, along with maximum
acceleration from a standstill when utilizing launch control mode). The
braking system offers enhanced performance-oriented pedal feel. Up/down
gearshift execution of the DCT and performance of the Super Hybrid
SH-AWD and active driver aids (VSA, AHA) are programmed to support
circuit limit driving, and an even greater amount of engine intake sound
permeates the cabin for a more heightened and emotional driving
experience offering enahanced driver feedback even when wearing a
helmet.
This setting also prioritizes the lithium-ion battery state-of-charge
to maintain a consistent level of torque delivery and direct yaw moment
from the three electric motors to ensure consistent dynamic response
and lap times.
Of note, the VSA operation is progressively "loosened" from the IDS
Quiet mode up to Track mode, enabling a progressively higher degree of
freedom for the driver in exploring the dynamic capabilities of the NSX.
In "Track" mode, the VSA system can also be completely disabled by the
driver. The NSX IDS system has the world's first custom setting menu
that allows the driver to configure the vehicle's mode during startup.
For example, drivers can program the car to always start in Quiet or
Sport mode, along with the ability to schedule the NSX to operate
exclusively in Quiet mode during any specified time period such as the
early morning to avoid waking the neighborhood.
CONCLUSION By combining timeless NSX values and
advanced technologies to create zero delay performance in all aspects of
the vehicle, the next generation 2017 Acura NSX represents a completely
new and uniquely Acura expression of what a supercar should be—with
superior ergonomics, groundbreaking design and supercar thrills every
day without compromise.
In challenging to create a
New Sports eXperience the
next generation NSX will provide an intense and personal connection
between the driver and machine that establishes a new and
paradigm-challenging definition of supercar performance.
